Conduit Bending and Installation Flashcards

What is the term for a conduit bend that rises from a horizontal run to connect to a box mounted on a wall?

Answer: Kick

A kick is a single bend that angles a conduit run to meet a box or enclosure offset from the original run direction.

When bending a three-bend saddle around a 2-inch obstruction, what are the three bend angles typically used?

Answer: 22.5°, 45°, 22.5°

A three-bend saddle uses 22.5°, 45°, and 22.5° bends to clear an obstruction while keeping the conduit run parallel.

The multiplier used to calculate the distance between bends when making a 30-degree offset is approximately:

Answer: 2.000

A 30-degree offset uses a multiplier of 2.0; the distance between bends equals the offset height multiplied by 2.0.

Rigid Metal Conduit (RMC) differs from Intermediate Metal Conduit (IMC) primarily in:

Answer: Wall thickness and weight

RMC has thicker walls than IMC, making it heavier but providing greater mechanical protection in harsh environments.

What does the 'shrink' of a conduit offset refer to?

Answer: The reduction in overall run length caused by the offset

Shrink is the amount by which a conduit run is shortened along its axis when an offset is added; it must be added to the mark location to hit the target.

PVC conduit installed outdoors and exposed to direct sunlight must be:

Answer: Listed as sunlight-resistant

NEC 352.12 requires that PVC conduit exposed to sunlight be listed as sunlight-resistant to prevent UV degradation.

What is the correct method for cutting threads on rigid metal conduit in the field?

Answer: Use a pipe threader with the correct die size and thread cutting oil

Field threading requires a properly sized die and cutting oil to produce clean, accurate NPT threads without damaging the conduit.
